To all whom t may concern:

Pie it known that ARTHUR i/V. Sivirrii, citizen of the United States, and resident of the borough of Manhattan, city oif N ew York, in the county of New York and State roi `New York, have invented certain new controlling separate work sheets or Acards in their movements with reference to the printing point.

The main object of my invention, generally stated, is to provide comparatively simple mechanism of the character specified which is reliable and efficient in operation and by means of which the separate sheets or cards may be'quickly positioned and filled in or written.-

Considered from a more specified aspect,

the invention may he said to have the following objects in view: (lst) to provide improved means for handling work sheets or cards in a Hat condition from the time they are introduced into the machine until they are` discharged therefron'i; (2nd) to provide .improved means by which al plurality of work sheets or cards may be moved along a container to a position from which they are conveyed from said container; (3rd) to provide improved means for feeding and guid ing the work sheets or cards to the printing line: (4th) to provide improved means for discharging the' work sheets or cards from the machine after th'ey have been lled in or written and after they leave the printing. line; (5th) to provide improved anto-` iiiaticallyojierating means by which difierent extents of feed of the work sheets or cards may be effected at different actuations et' a handle to provide the requisite feed for spacing between' lines and for bringing,r

new card into position to receive the first hiie ot' writing; (6th) to provide improved simple and effective means tor discharging written work sheets or cards from the ma` chine; (7th) to provide improved automatically operating means for arresting the carl riage at successively dilei'ent points at suc# cessive return movements of the carriage to' facilitate writing addresses on the werk sheets or cards; and (8th) to so construct Specification of Letters Patent.

The invention in the present instance is embodied in a stencil writing machine in which needle faced types are employed for impressing they outline of the characters thereon in the stencil sheets orA cards by puncturing them, the cards being afterward used in' an addressing machine. It should be' understood, however, that this represents but one embodiment of my invention and that it may be embodied in various styles of typcwriting machines, whatever the character of the printing or writing instrumentalities and whatever the character of the work sheets o'r cards employed or operated on. When, therefore, terms writing, typewriting, types, j printing instrumentalities,77 cards, 6r" `work sheets 7 or like terms are employed, thesey terms are used in a broad sense and are not confined to the specific forms V.of devices or articles shown.

The" frame of the machine comprises a base 1, corner posts 2 and top plate 3. The

type actions V'shown in ,the present insta-nceA each comprises a key lever 4 'fulcrumed on a fulcrum bar 'and extending forwardly to the keyboard of the machine where it is provided with a finger key 6. A' returning spring 7 is connected at one end to a plate 8 secured tothe base of the machine and at its` opposite end to the associated key lever. An upwardly extending link 9 connects each key lever with an'associated sublever 10 pivoted at 11 to a hanger 12. A rearwardly extending arm of each sub-lever 10 is connected to a link 13 which in turn is connected to the heel of the associated type b ar 14. rl`he various type bars are mounted on hangers 15 and are pivoted to swing upwardly and rearwardly to the printing point. The forward end of each type bar is' provided or formed with a socket 16 having a conical opening therein for the reception of a conical stem 17 of a type block 18. The so-called type block is formed as a cup-like member 19 which receives the needles 2O forming the type at their upper pointed ends. The needles may be secured in place in the socket19 by soft metal, as indicated at 21. A socket 22 surrounds each type bar socket 16 and extends downwardly therefrom to provide a bearing opening for a soft pad 23 made of felt or other suitable material. The pad 23 on each type bar is shown in the present instance as cylindrical in form and is of suicient area to receive the impact of any of the types formed by the needles 20. It will be observed that these pads normally rest upon a segmental type bar support 24 carried by the segment for the hangers 12and each pad constitutes a resilient support for the associated type bar. 1t will be understood that each pad 23 is so situated that it-will be presented, when its type bar is at the printing point, in a position so as to constitute an impact pad against which the needle faced types of any of the subsequently actuated bars may strike, Thus it will be understood that the pads 23 constitute means for preventing injury to the needle faced types in the event o f collision between the type bars at the printing point. The manner of constructing the needle faced types and the safety pads for preventing injury thereto are not of my invention.

The escapement mechanism is or may be of the ordinary construction such as that employed in the No. 10 or No. 1l Remington machine,- for example, and in which a universal bar 25 extends beneath the key levers 4 and is supported at its ends by links 26 which extend upwardly .therefrom to crank arms 27 whichV project rearwardly from the rock'shaft 28 pivoted to turn on bearing screws secured in the base of the machine. A centrally disposed rearwardly projecting crank arm 29 extends from the rock shaft 28 and is connected to an upwardlyr extending link 30. The upper end Aof this link is connected to a dog rocker 31 pivoted at 32 to a bracket 33. A feed dog 34 is carried by the dog rocker` and cooperates with a double escapement wheel 35 carried by an escapement wheel shaft 36 which turns in a bearing ,opening in a bracket 37 fixed to the top plate of the machine. A contractile spring 3S is connected at one end to a pin 39 which projects from the dog rocker and at its opposite end to a plate 40 secured to the bracket 33. The forward' end vof the escapement wheel shaft carries a' feed pinion 41 with which a feed rack 42 coperates. This feed rack is fixed to the carriage in a manner which will hereinafter more clearly appear. The carriage which is designated as a whole by the reference numeral 43 comprises a rectangular frame provided with a front grooved guide rail 44 and a rear grooved guide'rail 45..

Anti-friction balls or rollers 4G are received spacing plates 67.

propelled in its`step-by-step feed movement from right to left.` 1 l l A. platen 54 is in the present instancefixed tothe carriage to move therewith and comprises an oblong strip of felt or like material which presents a forward flat iinpact face to the front of the machine andwhich is adapted to receive the impact of the needle faced types. v.This platen is .received within a substantially U-shaped sheet metal container-56 fastened by screws 57 to a bar 58. rll`he bar 58 ,is fixed at its ends oy-screws 59 to. parallel supporting plates 60. These plates are fixedly connected by screws 6l to a horizontally disposed bar 62 which in turn is secured to the rear carriage rail 45 by screws 63. it will he seen, therefore, that the platen 54, plate or har 58, parallel side plates 60 Nand bar 62 are all iiXedly connected together and are secured to the carriage to move'therewith. f

A.-siip1)0it is provided on the carriage in the rear of and above the Aplaten for a plurality of work sheets or cards. In the present instance this support is in the nature of ay container, chute or hopper, designated-as a whole by the reference numeral 64 and comprises a bottom wall G5 Aand parallel side walls 66, which latter are preferably spaced apart toV correspond to the length of the work sheets or cards received in thev hopper. Each side wall (3G of the hopper is provided with a spacingplate 67 which-is riveted thereto as at G8. Screws 69 extend through the side plates 60 and are received in tapped openings 70 (see Fig. 8) in the The hopper is thus fixedly connected to the carriage and is supported at an inclination vto a horizontal plane, as shown in Fig. 4. The forward open end of the hopper terminates at a substantiallyl inverted Ushaped supporting plate 7l which is best shown in Figs. 4 and l1. The depending arms of this supporting plate are secured by screws 72 to the plate or bar 58. A rectangular opening 7 3 is thus provided in the supporting plate 7l but the body portion of the plate eXtends up in front of' the discharge end of the hopper and constitutes a. support for the work sheets or cards. In the present instance these work sheets or cards are in the nature of stencil plates or stencil cards each of whichv is designated as a whole by the reference numeral 74. Each card, in the present instance,.comprises a rectangular cardboard frame 75 covered on one side with a thin shret of paper lwhich may he pasted or otherwise allixcd to the rectangular frame 75. lFliese cards, as will he seen are arranged on end in the hopper (S4 and are sup ported one next to another against the supi'iorting' plate 71 at the forward und of the hopper.

I have provided automatically operating means for moving the cards along the hopper to the point of discharge therefrom. These means are' best shown in S, 4 and 7. the latter of which ligurcs shows the construction` in detail. The mechanism in question comprises a follower, which is designate'd as a. whole hy the reference numeral 77.- This follower comprises a hase 78 which is supported on the hase (l5 of the hopper and carries upwardly extending side plates 79 and upwardly extending front contact plates 80. The widthwise dimensions of the follower correspond substantially to the width of the hopper so that the follower is prevented from turning or sliewing in'its increment along 'the hopper. Froin'an inspection of Fig. 7 it will be seen that the Contact plates 8O of the follower are spaced' apart so as to provide an intermediate opening hetnveentheni while the front contact faces 'of these plates ai'e adapted to .hear against the group of cards contained in the hopper and force the cards toward the discharge end thereof. Y

Motion is transmitted to this folleweixby a. coiled spring 8l which surrounds a spindle carrying headed pivot screws 83 4which are received in hearing openings in the side walls 79 of the follower. A centrally disposed drum or disk 84 is iiXed on the rota- .tive spindle 82 and one end of the spring 8l is fixed to the drum, as indicated at 85. The opposite end 86 of the spring is fixed to one of the end plates 79 of the follower. rlhe force of this spring, therefore, is eX- erted to turn the drum 84 and spindle 82 in the direction of the arrows at Figs. 4 and 7. A band 87 is secured 4at one end to the drum or disk 84 and is connected at its opposite end as at 88 to the front edge of the bottoni wall of the hopper, as shown in Figs. 4 and 8. This end of the band is therefore anchored atA 88, whereas the opposite end thereof is connected to the drum 84. The power of the spring is effective to turn the drum and thus force the follower' as a whole along the hopper toward the discharge 'end thereof. in order to facilitate moving the follower aga-inst the power of its spring 8l in the opposite direction, l have provided the follower with a finger piece or loop .89 riveted at 90 to the base piece 78 of the follower. This finger piece or loop enables-the loperator to move the follower along the hopper toward the rear open end thereof when a new batch of cards is to be placed in the hopper. By releasing the hooked end 88 from its point of anchorage the follower as a whole may he removed from the machine. As indicatedin Fig. 7 I have provided a cut-outQl in the'hovttom wall of the follower to enable the bandto pass through such cutout cr "opening in order that the forward l end portion of the band may lie snug against CIK the bottom wall of the hopper and not interfere with the cards as they are fed along the hopper.

l have provided means for guiding and feeding the cards successively from the hopper to the platen while the cards remain in a flat condition and for discharging the cards from the machine after they pass the printing line and have been appropriately inscribed or written. The guiding means comprises two curved guiding surfaces 92 which are spaced apart and arranged so as to cooperate with the cards at opposite end portions thereof. The inner face of each guide 92 forms a continuous guiding surface which extends from thepoint 93 where it underlies a depending flaringp'rojection 94 (see Figs. 6 and 8) projecting from the bottom wall 65 of the hopper to the point 95 at which the cards are discharged from the machine. Each of these guides is secured to and projects inwardly from one of the supporting plates 60, screws 96 securing the guides to said plates. The guides are thus secured to theedges of the plates 60 and conform to the outline of theplates.

The feeding means comprise two drums' 97 and 98 which are substantially surrounded by the guides 92.v The drum 97 is fixed jto heads 99 and 100 (see Fig. 11) each provided with a central bearing opening for the reception of a shaft or spindle 101. The

spindle extends through a bearing opening in the left-hand supporting plate and is tapped at its end to receive a headed screw 102. The head 99 is provided with a feather or' projection 103 which is received in ai spline groove 104 in the shaft 101 so as to fixedly connect the turn together. The head 100 is frm'ed with a hub105 w hich is received in a bearing opening in the right-hand end plate 60. The drum 97 may be soldered or otherwise secured to the -he'ads 99 and 100. The

drum 97 near each end thereof is provided with a series of circularly arranged openings 106 in which projections 107, on two flexible endless bands or carriers 108 which surround the drum, are adapted to engage. The endless bands 108 also pass around the drum 98. This last mentioned drum is soldered or otherwise secured to heads 109 and 110, the latter of which is splined to a shaft 111 in the same manner as the head 99 of the drum 97. This shaft is supported in bearing openings in the supporting plates 60 and is tapped receive a headed screw 112. Thedrum 98 is also providedwith two series of circularly arranged apertures 119` in which-the projections 107 on the bands are adapted to engage so as to form-a positive connection between the two bands 108 and the drums 97 and 98. One of the endless bands or carrers 108 is shown in detail in Fig. 5,` Each shaft and head 99 to.`

at the left-hand end thereofto' carrier is preferably made of four strips of spring metal or other suitable resilient material. These strips are riveted together at 114 by the same rivets which secure the projections 107 to the endless band. Each strip is extended beyond the point of its connection 114 to form a resilient device, member or spring arm 115 which, as shown in Fig. 5, is tensioned to move toward a tangential position such as that shown. The

four strips of resilient metal of each .cari

rier thus united constitute the "endless band and also form four spring arms which 'are carried by or fixed to the band and Inove therewith and are adapted to have a movement independently of and relatively to the band, as will hereinafter more clearly appear. While the endless band is shown 'of circularform in Fig. 5, it will be understood that this is duc to the fact that it: is shown free from restraint in this' view and 'that when the band is in place upon the drums 97 and 98 it takes the shape or path il1ustrated in Figs. 4 and 6. In the construction of the band thus described'the arms 115 in fact form part of the endless band but forl convenience of description they will be treated as separate parts; that is to say, the

endless band will be described' as such and as carrying arms 115. It will'be seen that the free lend of each of the arms 115 is provided with a bent end or hook-like engaging portion 116 and that each arm also carries a projectionlor abutment 117. From an inspection of Fig. 4.it will be seen that Sil@y the space between the engaging portion 116 and the abutment 117 .on each of the bands is slightlygreater than the distance from the top From an inspection of Fig. 11 it will be observedthat the'bands 108 and the arms which are carried thereby are situated onl opposite sides of the supporting member 71 which supports the cards at the discharge end of the hopper 64.- Moreover it lwill be seen that the bands and spring arms are so situated that in the rotative movement of the bands the free ends of the arms 115` are adapted to co-act with the inner continu-- the guide mem@ ous guiding surfaces of bers 92.

In theiop'eration 'of this mechanism mo'- tion is transmitted to the shaft'111 in a manner to Ibe hereinafter described and this movement is effective to turn the riving drum 98. The rotative movement ofthe drum 98 is effective to'turnihe endless bands 108 and the cylinder or drullfV 97 around which they pass. 108 lia-ve the samerelati've disposition and the rot-itionof the drum 98 brings one` pair" of arms 115 to the full line position shown in Fig. 6. When the parts are thus disposed the hook-like engaging members 116 on these arms are located directly above the foremost I' to the bottom of oneof the cards. l

The armson.bothv bands.

in the hopper.

eurved guides 92, the arms contacting at lio ` arranged at the platen in a eeive the first line of writing, Whereas the their free ends with the guides and following a path of movement such as is indicated in Fig. 4. Four different Successive positions of a companion set of arms 115 are indicated in this View and designated by the reference characters o, 5,-@ and l respeo, tively. It will be understood from these diii'erent positions of the set of arms 115, especially .vlien compared with the setA of arms just above them which are moving a card fromthe hopper, that the spring arms of each band in some positions are se guided at ltheir free ends' that they contorni. substantially to the outline, surface or contour ot' the endless band in its movement around the drums, whereas in other positiions the spring arms are flexed at their tree ends away from the bands so that they assume 'different angular relations to the surface of the band. It will be understood from the positions a, Z1, o and (Z shown in Fig. fi that while the cards when they are :ted from the hopper move in a curved path 'around the drum 97 they nevertheless remain in a flat condition and continue to be engaged by the hook-like ends ofthe spring ar is which sweep around and contact- With the' inner guide faces of the. guides 92 to positivelj-,fY engage the cards and move them upwardly around the drum 97 to the platen This engagement between the spring arms and the cards is maintained during the movement of the cares around and past the platen and until after the c. rds have been written or inscribed and have leftthe platen vand (continued to the point of discharge. `50

From an inspection of Fig. ft i'tivill be seen that the parts are so disposed in this .view that one card has been moved doii'nn'ardly from the hopper, whereas a second card is engaged bv another set et arms at the lower portion et' the guides 92. A third card is position to refeurth card has been moved upwardly Afrom 'the platen and is about to discharge the.

saine from the machine. f A single line space movementot the ,carriers from thepesition shown in el' is eii'ect-ive to bring the third `card into position to receivev the second line of Writing, the parts at this time moving to the .positions shoivn in Fig. G.

lt Will be seen that in this view theaipper set oi arms has been treed from control oi the guides $72 by the lino .pace movement and has moved successively to the diiiierent Vpositions indicated respectively at o, j", y, /i

and This mort-,ment is due to the uihe-rentresiliency oi' the arms which moves them from the bent position around the cylinder or drinn 98 to the tangential position indicated at t' Where they are arrested. by contact with the first card i''t ot the group contained. within the, hopper. The' sudden relase of the flexed spring'arm: effected in the manner described, causes the 'card engaged thereby to' follow some sorti curved path ot movement as that indicatei by the different positions et the card T/l iu Fig. 6 and to shoot or propel the card 'with considerable torce rearwardly over the hopper and over vthe cards contained therein to a suitable receptacle A, as indicated by the dotted line in Fig. 10. This receptacle may be of any suitable character, although 1 have provided a special receptacle for this pui'- pose which comprises an upright box having the front Wall terminating at 118 and its rear and side Walls extending a considerable distance above the front wall in order to receive cards which may be shot or propelled from the machine. The Width of thisI re- Aceptacle is preferably suehtliat it is adapted to receive a card through the opening in the front ivall thereof, irrespective of the )osition of the carriage in its line oi trave I'have provided a plurality ot' so-called safety pins or contacts 119 which, as shown iii the present. instance, are oppositely dis'- of the cylinder or drum 97 about midway in the length thereof. The purpose of these pins is to prevent a Acard from being advanced by its spring arms too rapidly in the feed ot the cards through the machine, with the possibility of' the cards jamming. Thus,- ifroni an inspection et. Fig. 4C, it will be understood that if the released arms in moving -pesed on and vproject tromtlie outer surface iio successively from the positions a, b, and e to the position o7. should propel' the card ahead of the 'arms after the latter is arrested, there might be an opportunity lfor the advancing card to engage in the eonstrieted opening .or space between the guides-9:2 and the lower front .portion of the drum 97. However, the position oi one of the pins '119| .at this time prevents the upper edge of the card from entering the constricted opening and thus prevents any liability of a card choking between the guide and the cylinder at this point. f

i have provided means't'or intermittently rotating the shaft 111 in order to eti'ect a `rotative movement of thel carriers 108 to the v i AS provide for spacing between lines cards are being Written and to move the cards successively lupinte notonii front b 133 to of the platen to receive the first line of writing and to discharge the cards from the machine in the manner hereinbefore described. rllhe means for rotating the shaft 111 is as follows: A collar 120 is secured by :x set screw 121 on the shaft 111 to the right of the right-hand supporting plate 60. The shaft 111 is prolonged and receives a bearing at its right-hand end in a bracket plate 122 which is fixed by screws 123 to the right-'hand end bar of the carriage 43. From an inspection of Figs. 1- and 3 it'will be seen that a rock shaft 124 extends forwardly and then downwardly to provide a finger piece 125 by which the shaft may be rocked. A spring 124 surrounds the shaft and is contained within the bearing therefor. rl`his spring returns the shaft and the parts connected therewith to normal position. rlhis shaft receives a bearing in a bearing member 126 secured to therighthand end bar of the carriage. The rear end of the rock shaft has a` crank arm 127 fixed thereto. This crank arm is connected to a depending link 12S which is connected at its lowerend to one arm of a bell crank lever 129 pivoted on a pivot screw 130 which extends through a spacing sleeve 131 and is received in a tapped opening in a depending lug on the right-hand end bar of the carriaOe. 'An arm or slide 132 is pivoted at the other arm of the bell crank lever and is provided at its rear end portion with a. rack 134, the teeth of which extend from the inner side of the member 132. From an inspection of Figs. 12 and 13 it will be seen that the member 132 is slotted at beneath the rack, the slot extending ifore and aft of the machine. The shaft 111 extends through this slot so as to form a support for the rear end of the member 132 to support and guide it in its movements fore and aft of the machine. This rack overlies and is adapted to engage a pinion 13G which surrounds the shaft. 111. From an inspection of Fig. 11 it will be seen that this pinion has a hub-like portion 137 which bears at its end against the rack carrying member 132 to prevent a movement of the latter to the left. lThe pinion is also provided with a hub-like member 138 which is received in an 1 opening in a sleeve 139 and is secured there- The construction is such that the pinion 136,

- sidethereof. The pawl is thus arranged on to by a drive fit. A crank arm 140 is receivedon the left-hand reduced end of this sleeve and is ixedly connected thereto'by riveting up of the reduced end'of theV sleeve.

4sleeve 139 and crank arm 140 are Xed to turn together butl are free to turn on the 'shaft 111, A pawl or actuating member -141 is pivoted by a headed screw 142 to the outer end portion of the'crank arm at one oneside of the crank arm andoverlaps a mutilated spacing wheel 143, the engaging nose 144 of the pawl being adapted to en= gage the wheel, as will hereinafter more clearly appear'. This spacing wheel is shown in detail in Fig. 1S from which it will be seen that thewheel has two sets of teeth 145 and 145a on diametrically opposite sides thereof, three teeth lheilig provided in each set, these teeth being spaced apart a uniform distance. Intermediate these two sets of teeth there are formed two intermediate dwells 146 and 145` vThe effect, therefore, is to provide a long space between the last tooth of'each set of three teeth and the first tooth of the other set. The engaging nose of the pawl is adapted to ride on the dwells 146 and 146% as will hereinafter appear, the

pawl being forced toward the wheel by a spring 141EL (see Figs. 3 and 12). From an inspection of Fig. 11 it will be seen that this wheel 143 is provided with a huh 147 tapped to receive screws 148, the reduced ends 149 of which are adapted to be seated in openings in the shaft 111 to fixedly connect the wheel of the shaft.

Arranged adjacent, to the wheel 143 is a rotative controlling device, disk, toothed member. or shield 150 which is shown in detailin rig. 20. This controlling device is mounted to turn on the hub 147 ofthe wheel v.

143 and is connected to the wheel by means of headed screws 151 which extend through vslots 152 in the controlling device and are received at their ends in tapped openings in the wheel 143. It will be observed from an inspection of Fig. 20 that the controlling device is cut out on the side next to the wheel 143 to receive a C-spring 153 which bears at one end against a shoulder 154 formed o n the controlling member, the opposite end of the spring bearing against one of the screws 151. The force of this spring is exerted to normally maintain the controlling member in a reta-tive position with reference to the wheel 143 where one end of each slot 152 bears against its associated screw 151, as indicated in Fig. 12. On diametrically opposite sides of the controlling member 150 are formed dwells 155 and 155g. Ratchet teeth 156 and 156a are formed on the member 150, one in the rear of each dwell. The construction is such that the pawl 141 is adapted-to coperate with the controlling member, as well as with the wheel 143, the width of the pawl being 'equal to the two members 143 and 150. A spring detent 157 (Fig. 16) is secured by a screw 158 to the rear cross'bar or guide rail ment of the iingzrjer piece 125 to the right eii'ects a rotative movement of the rock shaft 124, thus transmitting movement through thel link 128, bell crank 129 and arm 132 to the raclr134, moving the latter rearwardly. The'effect of this movement is to turnpthe pinion 13G and to effect a corresponding rotating movement of the crank arm 140, thereby moving said crank arm and pawl 141 from the position shown in full lines in Fig. 12 to that indicated in Fig. 13. This movement is effective to turn the shaft 111, the drum 98 positively connected thereto Yan d the rotative carriers or bandsf108, the bands rotating from rightto left as the parts appear in Fig. 4. This is effective to move the cards successively from the hopper to the platen and finally to shoot the-cards from abovethe hopper to the receptacle A, 'as hereinbefore explained.

The controlling device 150 automatically regulates or determines the point in the throw of the pawl141 where engagement is effected between said pawl and the line spacing wheel. 143. In order to facilitate an understanding of thej operation of this automatically actuated controlling member, it

may be well to point out that jFigs. 1, 3, 4,

9, 11 and 12 represent the parts as they are disposed when a stencil card is positioned to receive the first line of writing, or immediately after the first line of writing has been completed, whereas Figs. 6 and 14 represent the parts as 'they are disposed when a card isin position to receive the secondline of writing or immediately after said line has been completed, whereas Fig. 16 represents the parts as they are disposed when a card is positioned to receive a third line of writing or immediately aftersaid third line has been written. With this understanding special reference is made'to Fig. 12. Assuming that the parts represented in this figure, as shown in full lines, disclose the parts as they -appear immediately after the first line has been completed, the operator will grasp the handle 125, moving it and the carriage to the right, thereby rocking the shaft 124 and effecting a rearward movement' of the rack 134- through the intermediate connections, in the'manner hereinbefore explained. This rotative movement ofthe crank arm 140 from the full line position shown in Fig. 12- causes the pawl 141 to ride over the dwell 146'on which the pawl rests. It will be seen that as the parts are disposed in Fig. 12 the dwell 155 forms in eli'ect a continuation of the Adwell 146 on which the pawl rises from the full line position., At this time the dwell 155-registers with ,the opening which is just in advance of the third of the teeth. 145 onthe line spacing wheel The. controlling member thereforeprevents the pawlfrom entering this notch `in advance of the third tooth 145 but as the pawl reaches the dotted line position together independently of the line spacing wheel until the pawl is brought into enga ement with the second tooth 145 on the line spacing wheel, when the line spacing wheel and controllingl member will be caused to turn together a distance corresponding to a vline feed movement between the first andv second lines on thestencil card.l Fig. 13 represents the parts as they appear at the completion of this movement. i From this gurey it will be seen that the spring detent 157 has l snapped back of and is interposed in the path of the tooth 156a on the controlling member so as to prevent a return movement of said controlling member under the action of its spring 153. The controlling member therefore is retained in the rotative position to which it has been moved by the pawl 141 while the pawl and arm 140 return lto normal position when the operator releases the handle and the 'latter is returned to nor.- mal position under the action of its spring 124% The operator will next proceed to write the second line on the stencil card which at this time is properly positioned to receive the second line of writing. is completed the parts represented in Fig. 14 will be disposed as shown in this figure. The operator will then actuate the handle 125 in the manner hereinbefore described, re`

turning the earriageto the right to begin a After .this line Y new line of writing and automatically ac` f mating the crank arm to move it 'from the position shown in Fig. 14 to that indicated in Fig. 16. It will be seen from Fig.

14 that prior to this actuation the controlling member 150, in its previous shifting' movement, has changed its position relatively 4to the line spacing wheel so that the dwell' 155 on the controlling member no longer forms a continuation of the dwell 146 and no, longer completely covers the opening in advance of the third tooth on the line spacing wheel. Therefore when the pawl 141 reaches the opening in advance of the third tooth it enters this` opening and engages the abrupt forward face which connects the dwell to the body portion of the controlling member. The further movement of the pawl141 will therefore advance the controlling member relatively to the line Lil with which it eneao'es bv a s rin@ 141 l )ath of movement which is indicated by the J 2T v b e which. as will bc understood from an inspection or' Figs. 3 and 12. le ixeil at one end by a screw 168 to the crank arm 140 and han an angular extension or projection 169 at its tree end which overlaps and bears against ihr pov-'l 111 near the engaging nose of the latter.

The carriage is adapted to move over the top plate and to carriY with it the platen, the card feeding devices and the hopper. The

range ot this movement of the carriage con responds approximately to the length oi a,

line to'lie written on the stencil Sheet 7G within the frame 75 of a card. The movement of the carriage from right to left or in the direction of its *feed will be arrested by a stop 170 (Fig. 3) secured to the top plate or the machine by a screw 171 and adapted to engage. at its" ends the left-hand side or fisuppirtinp; plate and thus limit the niovement of the carriage.

ln the present construction I hare pro-- vided automatically operating means for variahly :ii-renting the carriage in its return movement to begin a new line ol2 writing, the carriage beingarreol'ed at positions which are progressively nearer vthe center of the machine at different return movements of the carriage. This margin stop mechanism heel illustrated in Figs. 11 and 21 to 4- inclusive. the last mentioned group of 'ei'uies Showing` the detailsof the eonetiuc` lion. A bracket 172 is Secured to the righthand supporting .plate GO by screws 173. This bracket has an arm 1711- whicli extends to the right and constitutes n support Jor a .ecrcw pivot 175. From an inspection of Fig. Q it will he seen that this screw 175 passes freely through an opening-.in one Side member orear 176 of a sheet metal pawl or etno member designatedas a whole by the rerereiice numeral 177. The opposite parallel wall 178 of this pawl is tapped to. ref

eeive the threaded end 17,() of the pivot screw 175. This4 screw-valso passes freely through au openingin the projection 174 and receives a bearing therein b v which the pawl in pivotally supported inplace. Theupper wall ot' the pawl which joins the two side members 176 and 178 is adapted to bear upon 3 seriesof teeth or stops 184i,l 185 and 186.

the upper surface of the projection 17 f1 (Fig.

11) to limit the downward movement of the.

pawl. l This pawl oistop member has an engaging nose 180.

A bracket plate 181' 4is secured by'screws 182 to the top plate 3V of the machine near the iighthand side thereof. The bracket plate is foi'iiied with an `upwardly eXtend'-.

,-'nig plate-like projection183 provided with n These Stops sire in the. nat-ure of ratchet teeth which incline from right to left and form in effect a ratchet bar or rack. The'pawl 177, traveling' With't-he carriage; normallyiliae a ,i iofiee dotted line showin@ of said pawl in Fig. 22. The upper v edge of the nlate 183 at the inner cnd'ot'the pawl is brought into cooperation with the bevel. Ordinarily an arrest ofthe carriage would be effected by the pawl enteringi the space to the left of the tooth 1.84 which is the llrst tooth the pawl 'would encounter in'its morement to theright with the carrizi'ee. However, I have provided controlling means for controllinoithe cngagenient oi the pawi with the dillerent Stops or teeth 18115 185 and 186. Thecontrolling means in the present instance comprises a controlling member. device or shield 188 which is in the nature 'a Slide and has a rectilinear movement, being supported by headed Lsere-ws 189 whichextend through e. Slot 19@ and are received it their threaded ends in tapped openings in the plete 183. 'This sliding plete is provided with three teeth or engaging portions 191, 192 and193.'

tractile spiiig 197 is connected at one 'end to a'. pin or hook 198 which projects from the plate 183, the opposite end oi the spring being' connected-lo a pin 19S) which projects tram one side of the controllingmember .188. rThe force of this spring is exerted to pull the controlling member to the left.

."*L pawl 200 is pivoted by' a headed screw 201 to the controlling member; The engaging nose 202 o1 this pawl is adapted to co-k :ict with ratchet teeth 208 formed on abloek 204 which is ixed tothe plate 183 by screws 205. The ratchet teeth 203 terminate'a in a cam 206 the block and with which the engaging nose 'on the pawl is adapted to co-zict. This pawl is forced into engagement with its ratchet teeth by a wire spring O7 liXed at one end to,tlie"controlling member 188 by e Screw .208. The opposite end o1c the spring-inreceived in an opening 20?; (see Fig. 22) formed in the pawl 200. A leaf spring 210 is fixed to the bracket plate 181 by rivets 211. The left-hand. end of this spring is bent forwardly and then upwardly and then rearwardly to form o flat upper portion 212 which overlies the epgziging nose of the pawl 200 andforms a controlling device.

Normally the portion 212 of the spring 21? is free from engagement with the nose 202 of the pawl but as the controlling member ire moved to the right relatively to the stop carrying member 1887 the engaging portion oi the pewl will be brought into contnct with the lower face of the part of the spring, es shown inFig. 23, thus elevating the free end of the spring. A. movement el' .the controlling member from the position formed on the upper front edge of llO refe f ed to contact with the upper side of the partl 212 of the spring, thereby maintaining the pawl out of engagementv With the ratchet teeth 208 during the return movement ot the controlling member188\-,\as\indicated by dotted lines in Fig. 211. It being understood that Fig. 21 shows the normal positions of the parts, and that these parts are -glisposed as shown When the carriage is `moved to' the right to begin; the first line of .,rriting, it will be seen that in this movennent of the carriage the paWl 177 Will engage the dwells 1.94 and 195 on the controlling member, the pawl thereby being prevented from entering the notches of the tirst two teeth 184 and 185 but that When the pawl reaches the opening in front of the tooth 186 it will enter this opening, engaging the face 193 on the controlling member and moving said member to the right with the stop or pawl 177 until the latter is arrested by engaging the iXed stop 186. This movement of the controlling member 1s etl'ective to carry the paWl 200 with it from.

the position shownin Fig. 21 to that represented in Fig. 22, which shows the disposition of the parts at the termination of the movement of the carriage to the right to begin the first line of Writing. The vpawl 200 engaging the first of the teeth 203 Will retain the controlling device 188 in the position to which it has been shifted. The operatorproceeds to 'Write the lirst o. name line and when this is completed the operator will again move the carriage to the right through an actuationot the handle 125 and at this time the controlling device 188 being in the position shown in Fig. 22 the dwell 19i- Will prevent the pavfl 1,77 from engaging the notch in advance of the first tooth 184 but will enable the paivl to enter the notch in advance of the tooth 185. As the i` pawl enters this second notch it will engage the contact portion 192 on the controlling device, thus moving the controlling device- I figure shows the disposition of the parts at the termination et the second return movement of the carriage'to begin the second line ot' Writing.

A comparison of Figs. 22 and 23 will show that the carriage is arrested in its second return movement at an earlier period than in the return of the carriage for the irstline of Writing, thus properly arresting the carriage'so as to oiiset the beginning of the second lineor the first line of the ad- At this time the engaging portion 1,1 ione@c dress. The parts are substantially in the position represented inv Fig. 23 when the carriage is returned the second time. This will leave the controlling member 188 in the position shownin Fig. 23, Where the dwell notch in advance of the first tooth 184: and

will engage the face or contact portion 191 on the controlling member, forcing the latter to the right and carrying with it the pawl 200. The pawl 200 at this time moves up the incline 206 and releases itself from engagement with the spring member 212, as shown in Fig. 24. This View represents the parts as they appear at the termination of the return movement of the carriage to begin the third line of Writing. As hereinbefore explained, when the controlling portion 212 is lifted by the engaging nose'202 of the pawl 200, in themovement of the latter to the position shown in fulllines in Fig. 24, the part 212, as soon as released from the control lof the pawl 200, Will be returned to normal .position by its sprin thepawl 200 is prevented during the returnv movement of Athe controlling device 188 from engaging with the ratchet teeth 203. As the carriage. moves to the left in Writing the third line the controlling device 188 under the power of its spring 197 will move to the left until the right-hand end of the slot 190 in the controlllng member engage the right-hand screw 189.

At about the termination of the return movement of the slide 188 the pawl Will pass the left-hand end of the contact member 212 and will be forced ,to the lowermost position shown in Fig. 21. It Will be Seen, therefore, that during the Writing of the third line the controlling device 188 and thepawl 200 will return to the normal position which they occupied prior to returning the carriage Jfor beginning the first line of writing. It will be understood that the arrest of the carriagel in its movement to the right, through the cooperation of the paWl 17 7 sri 210 so lthat i with the stop or tooth 184.-, effects an arrest Y' .left-hand side of the machine while arrestail 217 to the top plate of the machine.

anions@ 11 ing the carriage preparatory to yvriting'the three lines to be inscribed en the stencil plate. While l have shown but three stops 18st, 185 and 186, it should be understood that any suitable number of suoli stops mayv be employed, appropriate modification of the controlling member 188 being made accordingly.

The range of the carriage movement, as' hereinbefore explained, corresponds substantially to the length of the card or to the dimensions of the card from one side edge thereof to the other. .lt should be understood, therefore, that the feed rack 42 need only be of a corresponding length. This will best be understood from reference to Figs.

1, land 9, from which it will be seen that the. feed rack 42 is securedfJ to the bar 62 by screws 213.

` Referring to Figs. l and 3, it will be observed that I have provided a repulser to prevent the type bars from stickingat the printing point when a needle faced type punctures the stencil sheet. In the present instance this repulser comprises a spring Wire 214 which extends horizontally across the type basket below the printing line. This spring Wire 214 is connected at its ends to contractile springs 215 Which in turn are connected to brackets 216 secured by screws The wire 214 extends into the path of all of the type bars in their movements to the printing position and' is adapted to be flexed by the type bars in such movements, the re-action of the spring Wire 214 and the coiled springs 215 insuring a release ofthe needle faced type from the stencil sheet and a quick return of the actuated type bar to the type rest.

Having described the construction and ar rangement of the various parts, a brief description of the operation of the machine as a. Whole will be given. Understanding that Figs. 1, 3, L1, 9, 11, 12 and 22 represent the parts'substantially as they appear after the first line of Writing on a card has been produced1 the operator Will actuate the handle 125, thereby returning the carriage to theright to effect a single line spacing operation of the feed devices to. bring the card at the platen in position to receive the second line of writing. At this .time the previously 7ritten card is discharged from the machine into the receiving receptacle A., as shown in Figs. G and l0. The controlling member 15 0 of`the line spacing mechanism is automatically shifted in the manner hereinbefore described by this operation asis the controlling member'188 of the margin stop mechanism. he second line is Written on the card at the nting line and as the carriage is again the parte will be disposed as they are represented in Figs. 6, 14 and 23. This nted to the right to begin a new line of movement again automatically eects an actuation of the controlling member 150 of the line spacing mechanismy in the manner hereinbefore explained and also automatically eiiects an actuation of the controlling member 188 of the margin stop mechanism.

he third line is then Written, the parts appearing as represented in Figs. 16 and 2a,

i the last mentioned ligure showing the parts disposed as they appear after the line has been completed and the carriage has again been returned to the right through an actuation of the handle125. This actuation of the handle is eifective to produce a long feed movement of the endless carriers or bands 108 to bring the next card to be Written into position opposite the laten to ref. ceive the `first line of Writing thereon. The same moven'ient brings about a reestablishment 0f the normal relation between the controlling member 150 and the line spacing ratchet wheel 1113, as has been previously described. It also brings about a reestablishn ment of the normal relation between the controlling member 188 of then'iargin stop mechanism and the arresting means les with which the margin stop or pawl 173? co-acts.

The cards are thus fechsuccessivcly `from t'hliY hopper in a curved path around and beneath the platen and are broughtsuccessixely into position in front of the platen to receive the impact of the upwardly and .rearwardly striking type bars against the front face.A of the platen, and as'the actuating handle is operated to move the` card attheprinting line into position to receive the .second ,line of writing, the previously Written card will be automaticallyv discharged liron'rthe machine. lt will be seen that the cards in. their feed movements from thehopper to the point or" discharge are guided and i. in a curved circuit around the platen nevertheless are maintained at all times in a flat condition.

The control of the parts is entirely automatic under an actuation of the handle the controllingmembcrf'lf) operating automatically to determinethe extent of feed which may be transmitted `to the card feeding devices to bring them successiif'ely to the printing line to effect a line spacing more-l ment of the card at the printing line and to discharge the cardsfrom the machine. The contro-lling memberlSS of the margin stop mechanism is also automatically 'controlled to bring about an arrest of the carriage at successive movements thereof to the right at positions Which-are successivelyv nearer the left-hand side ,of` the 'machine in order to arrest the carriage at the proper positions to begin the different lines of the name and address vto be Written on the Cardi Moreover, the return ofjthe controlling de vices 150 and 188 to their normal positions vrelatively to the members l'fland 183 reice spectively is automatically brought about during the return movement of the carriage under control oit the handle 125 after the third line on the card has been Written.- In short, the operator merely has to actuate the handle 125 successively to return the carriage to begin a new line ot` writing and to write the names and addresses on the .cards The control of the cards otherwise l in their movements from the support or hopper to the point of discharge is automatic'ally eiected. By this construction the mind of the operator is entirely relieved of l any Work incident to the proper positioning 15 of the cards and the removal thereof from the machine and `the cards may be rapidly Written and positioned in the machine with mechanical accuracy to receive the' diierent lines of writing on each card.

From the foregoing description it will be understood that I have provided a simple front strike Writin machine in which the stencil writing is e ected in full view ot the operator; that the cards are ncverhandled by the operator except to' fill the supply 4hopper; that the cards remain in a fiat condition in their passage through the machine: that there is no .liability of injuring the thin stencil sheets on the 'cards in the passage of the latter through the machine, and

that the machine is highly etlicient in use and enables an operator towritc a large number of cards iu a short time since none of the operators time is occupied in introducing the cards individually into the machine, positioning them therein and removing them after they are written.

The mechanism for effecting a feed of the cards and thenlargin stop mechanism of the" present invention have many features in common andl there are generic claims iucluded herein which may be predicated equally Well on either construction. Thus cach mechanism includes a toothed device,

a cooperating iawl, and automatically op erating control ing means for determining with which tooth of the toothed device sa id pawl or co-acting member shall coperate. Each mechanism also includes means for revstraining thecontrolling' means in different positions to which it may be shifted, or a detent for holding the controlling' member against the power ot' its spring, and also automatically operating .means for reestablishing the normal relation between the contro-lling member and the toothed member after a given number of actuationsl of said controlling member. In each case the controlling member is in the nature of a vtoothed device which is actuated by the same pawl that co-acts with'the other'toothed member. In 'each case the controlling memberis in the nature of a shield which prevents the cooperating pawl from engaging certain teeth rimase of a toothed member and in each r e the 5e' shield is automatically actuated to determine with which tooth of the toothed inember the-pawl shall engage. In cach case the pawl (141 or 177) coperatcs with a toothed member which is in the nature of a rack. It will be understood, therefore, that various changes may be made inthe 'construction and the action of the devices without departing from the spirit of' my invention, and that certain of the devicesl Amay be employed without others. Thus 4from certain aspects of my invention it is immaterial what character of means are employe-d to rotate the endless carrier and from certain other aspects voif the inv ion ge 'it is immaterial what form of mechanism is controlled by the devices shown in l2 to 2O and in Figs. 2l to 24.
